АДАПТАЦИОННЫЕ ВОЗМОЖНОСТИ ОРГАНИЗМА ЖЕНЩИН С ФИЗИОЛОГИЧЕСКИ ВОЗНИКШЕЙ БЕРЕМЕННОСТЬЮ И ПРИ ЭКСТРАКОРПОРАЛЬНОМ ОПЛОДОТВОРЕНИИ

Abstract

The study of the restructuring of the body of a pregnant woman with relation to the theory of functional systems is necessary for a complete understanding of the formation of adaptive processes. Of particular interest is pregnancy resulting from extracorporeal fertilization (IVF). Aim. to estimate the adaptive capacity of women with physiological pregnancy and IVF. Materials and methods. The object of the study: healthy women before pregnancy and in the I trimester (I group), patients with tubal-peritoneal infertility at the planning stage and after an effective IVF (II group), women with an unsuccessful IVF (III group). We conducted a study of the functional state of the cardiovascular system of pregnant women with the calculation of adaptive potential (AP) by R. M. Bayevsky. We assessed the regulation of the vegetative nervous system — Kerdo index (KI). We determined the state of regulatory systems with the stress index (L.H. Garkavi et al.). Results. In patients with physiological pregnancy, we noted the effect on the cardiovascular system of the autonomic nervous system and the tension of adaptive reactions. In pregnant women with IVF we recorded the depletion of adaptive activity of the sympathetic autonomic nervous system. This led to a significant strain or failure of adaptation with the predominant influence of the parasympathetic autonomic nervous system. Conclusion. Significant differences in the studied parameters in women with ineffective IVF program at the stage of pregnancy planning may have important prognostic value for determining the tactics of management of patients.
